What is a resistor array?

A resistor array is a component that houses multiple resistors within a single package. The resistors are usually independent of one another and can be wired separately, but they are commonly used together on the same board. This component simplifies circuit design and reduces the number of individual parts needed. Resistor arrays are particularly useful when multiple resistors of the same value are required, such as in voltage dividers or filter circuits. They also come in surface-mount (SMT) types, which enhance assembly efficiency and support compact circuit designs.

Application of resistor array

✅ Voltage divider circuit
Resistor arrays are useful when multiple resistors of the same value are needed, such as in a voltage divider circuit where several resistors are used in series or parallel.
✅ Filter circuits
In high-frequency or low-frequency circuits, resistor arrays are used to combine multiple resistors for filtering applications.
✅ Consistent signal adjustment
They are used when consistent resistance values are required across multiple signal lines.
